(Phys.org)—In 2014, the incorporation of two artificial letters of genetic code into the DNA of Escherichia coli gave the bacteria the distinction of becoming the world's first stable semisynthetic organism.
While fluorescence imaging (in which external light is used to excite a specimen that then emits light in response) is essential in cell biology, it has a number of significant drawbacks, including autofluorescence, phototoxicity ...
It has often been said that solar cells are like artificial versions of the photosynthetic apparatuses found in plants, such as leaves, since both harvest sunlight. But nature's leaves can do something that most solar cells ...
(PhysOrg.com) -- Scientists have developed a lighting device that can change its color temperature throughout the day, matching the natural daylight chromaticities produced by the sun. Currently, no other type of lighting ...
A group of researchers at the Technical University of Munich (TUM) has developed the world's first microrobot ("microbot") capable of navigating within groups of cells and stimulating individual cells. Berna Özkale Edelmann, ...

While classical and quantum electrodynamics present the existence of dipole-dipole long-range electrodynamics forces, they remain to be experimentally observed. The discovery of completely new and unanticipated forces that ...
New research from North Carolina State University demonstrates that genes are capable of identifying and responding to coded information in light signals, as well as filtering out some signals entirely. The study shows how ...

Inside a cell, tentacled vesicles shuttle cargo for sorting. DNA rearranges in the nucleus as stem cells differentiate into neurons. Neighboring neurons cling to one another through a web-like interface. And a new microscopy ...
